Supernova 2022an in Centaurus

[theskyhound]

Phil, this isn't real. SN 2022an is currently magnitude 16. Sadly, its not possible for an extragalactic supernova to be as bright as 0.3 magnitude. Looking at the magnitude history for this object in SkyTools, I see that there was a magnitude of 0.0 read from the Bright Supernovae observations page on February 9. This is an obvious error, but it isn't one easily recognize by the code, because it is possible for a galactic supernova to be magnitude zero.

This is the source of the supernovae magnitudes:

Always a good idea to check the source.
